Marble Jars

We are trying this positive discipline/reinforcement system for Siena. I feel like I give in to her too much and she gets whatever she wants whenever. She skipped the terrible 2's and I thought I was clear of it...apparently it's the terrible 3's for her. I have had many time out days lately for her and me. A coupe friends have tried this method and it seems to work for them. Why not try. So we are starting to fill this jar with marbles when she does nice things, like listening and obeying the first time, being nice to Ben, cleaning her room and toys up and staying dry all day, no accidents. I took her to the Disney store a while ago and she was amazed! She had no idea that that many princess things existed and she said she wanted everything. So when she fills up her marble jar she can go pick something out. She changes her mind everyday about what she wants but it is always something princess. So we were at Target and I saw a cute dress that I wanted for me and I told her it was cute and that I wanted it and she said that I should tell daddy and that I could have it once I filled up my marble jar! Hopefully I would fill up my marble jar a lot faster than she is filling up hers.
